Q

What is the primary and secondary MOA for alpha agonists?

Q

What is Iopidine (apraclonidine) derived from? Who is it contraindicated in? What is the onset of action? When is the max IOP reduction?

A

Derived from oral clonidine which is HTN drug.
Contraindicated in patients with hypersensitivity to clonidine, patients taking MAOIs.
Onset of action in one hour, good for office emergencies. Max effect in 3 hours.

Q

When would we use Iopidine?
How much decrease in IOP?

A

Control/prevent post-surgical elevations in IOP or if patient has emergency high IOP because it works in 1 hour. Can also be used as additive therapy BID for chronic glaucoma and need something else.
Used to diagnose Horner’s Syndrome. Will reverse the ptosis.
20-30% decrease

Q

What are some clinical uses of Alphagan (brimonidine)?
What percent decrease in IOP?
What is the dosing as a drop by itself?
What is the dosing if added to something else?

A

Primary open angle glaucoma
Ocular hypertension
26% decrease
TID by itself
BID with other drug

18
Q

What is a different ocular side effect does brimonidine have compared to iopidine (apraclonidine)?

A

Brimonidine causes miosis (shrinking of pupil) rather than mydriasis

19
Q

What medication does Lumify have in it?

A

Brimonidine.
Causes vasoconstriction and can last hours. Doesn’t have enough concentration to affect IOP.

20
Q

What alpha agonist can you use for better night vision?

A

Brimonidine (Alphagan)
Since it shrinks pupil size, it helps at night.

21
Q

When is Alphagan (Brimonidine) contraindicated?

A

Less than 2 years old.
Contraindicated in MAOIs and tricyclic antidepressants.
Sever cardiovascular disease and vascular insufficiency.

22
Q

What two drugs does Simbrinza have in it?

A

Brimonidine (alpha agonist) and Brinzolamide (CAI)

23
Q

What are CAI approved for?

A

Open angle glaucoma
Ocular hypertension

24
Q

What CAI is a suspension and must shake before using?

A

Azopt (brinzolamide)

25
Q

What percent decrease in IOP for CAI?

A

15-20%

26
Q

If using CAI by itself, what is dosing regimen? If used with another treatment?

A

By itself, TId
With other drug, BID

27
Q

What two meds are in Cosopt? What percent IOP decrease? What is the dosing? Is it available for preservative free?

A

Cosopt= timolol and dorzolamide
27% decrease in IOP
BID dosing
It is available in preservative free (cosopt PF, single until dose)

28
Q

What percent decrease in Azopt (brinzolamide)?
What is the dosing?
Is it solution or suspension?
Is it more or less comfortable than Trusopt?

A

15-20%
BID/TID are equivalent
Suspension
More comfortable than Trusopt

29
Q

What glaucoma med is a great add on with prostaglandin?

A

CAI, rarely used by itself

30
Q

What is the 1st combo drop that does not have a beta blocker? Is it solution or suspension? What is the dosing by itself and as adjunct therapy?

A

Simbrinza (brinzolamide and brimonidine)
Suspension due to brinzolamide
TID by itself, BID as adjunct

31
Q

What combo drop would you use for glaucoma if the patient has asthma or congenital heart failure?

A

Simbrinza (brimonidine and Brinzolamide)

32
Q

What are 5 ocular side effects with topical CAI?

A

Burning/stinging (less with azopt)
Blur - more with azopt
SPK, tearing, dryness, photophobia
Allergic reactions (10%) if sulfa allergy
Corneal edema (trusopt)

33
Q

Dose 2 250 mg tablets PO
Rx: 1 250 mg tablet PO every day

37
Q

What drug can be used to treat macular edema and Idiopathic intracranial hypertension?

A

Diamox (acetazolamide)

38
Q

If you had to use an oral CAI for chronic glaucoma, what would you prescribe? What percent IOP decrease?

A

Methazolamide
30-40% decrease

39
Q
